What are the differences of waterproof watches
by HongRong L. ceramicslifeHere are two kinds of waterproof
watches: Ordinary waterproof and professional waterproof.
waterproof watches rely on mirrors,
rear, watches, etc. waterproof apron and head to achieve the appropriate standard. All watches are waterproof cover on the
bottom playing a "WATERRESISTANT"
words in English or "WATER PROOF" of. No water mark watches means only dustproof, which should avoid cleaning
the bathroom. 30 meters (3ATM,
ie 3 atm) waterproof watches can
be used for daily grooming
or rain use, that
just splashing water
droplets on the surface and
do not have any pressure is applied to the table. 50 m water table is
applicable to swimming and general
housework, 100 meters waterproof watches can
be used for swimming and diving
underwater work.
So why waterproof watches marked higher than the actual
use ?
Usually waterproof watches warranty or instructions
for use in both this text:
Waterproof 30 meters, only anti-wash splashing;
Waterproof 100 meters, for snorkeling or
swimming;
Waterproof 200 meters, you can supply the lungs diving.
These instructions may seem clear, but fuzzy, like scuba
diving depth of 30
meters, however, why the need waterproof
to a depth of 200 meters waterproof
watch? Since waterproof up to
30 meters, so why not take a bath
wearing a watch? Exactly
how to interpret? Whenever
underwater 10 meters depth increases, it will increase the equivalent of one atmosphere of pressure, in
accordance with this principle, so
that the general pressure gauge
to test the watch factory are waterproof watches,
so some waterproof watches factory will to
indicate compression values (bar or atm) to represent its water values.
1bar equal to withstand
the pressure of one kilogram per square centimeter, it can withstand compressive 10bar pressure equivalent
to the depth of 100 meters
below the surface that exists,
which is waterproof 100 meters,
20bar equivalent waterproof 200 meters, and so on. If the watch is only when
the words Water Resistance without numerical mark,
in accordance with international standards
is a waterproof 20
meters. However, the so-called
stress test is static, when worn on the wrist using
a table or swimming diving, the pressure is
dynamic, so watch needed to withstand much
greater than the static pressure
of the moment, it must be multiplied by
the number fold safety factor to ensure watches waterproof, which is why the waterproof watches
marked depth is
much higher than the actual reason
for use.
waterproof watches performance difference:
Difference waterproof watches, the easiest way is by the shape determination: In general,
the best waterproof watches is circular watch,the second oval, and square or irregular
watch is relatively
poor waterproof , this is because
most waterproof apron and rounded close
together. Secondly, the material difference,
copper, aluminum or gold material for a
long time will deteriorate,
thereby affecting water resistance. Furthermore,
the crown, the bottom
and edges of the glass are the main local water,
so the watch itself is also designed to
have absolute influence, for example: with screw-in crown and case back with
bezel design, good compared thick waterproof
watches are usually better; ultra-thin waterproof
watches due to limited
space can not effectively waterproof,
so less water
resistance; according to the
design and versatile,
waterproof watches also likely to have loopholes.
